Overtone GEQ is designed as an efficient graphic equalizer that allows quick shaping of mixes and sub-mixes with precision. Its 7-band equalizer offers a gain range of plus or minus 12 dB per band, enabling detailed tonal adjustments across the frequency spectrum. The interface provides two graphic equalizer views to streamline workflow and enhance user experience during sound shaping.

Beyond basic equalization, Overtone GEQ incorporates harmonic enhancement processing to add a distinct character and brightness to audio signals. This harmonic coloration enriches the sound, delivering a polished and vibrant finish that stands out in a mix. The plugin supports multi-channel processing, including internal channel routing and channel grouping, allowing flexible handling of complex audio arrangements.

Additional features include mid/side processing for precise stereo field control, 64-bit floating point processing for high audio fidelity, and a robust preset manager to save and recall settings easily. The plugin also offers undo and redo history, A/B comparisons, and contextual hint messages to aid users at every step. Overall, Overtone GEQ combines straightforward equalization with advanced harmonic shaping tools to enhance audio production workflows.
